         2 . The server device according to  claim 1 , wherein the person under restriction and the instructor are different from each other. 
     
     
         3 . The server device according to  claim 1 , wherein the person-under-restriction related information includes information unique to the person under restriction. 
     
     
         4 . The server device according to  claim 1 , wherein
 the person under restriction is a person who provides a predetermined service to the instructor, and   the person-under-restriction related information includes identification information for specifying the person under restriction or a company to which the person under restriction belongs.   
     
     
         5 . The server device according to  claim 4 , wherein the usage related information includes content information indicating a content of the predetermined service selected by the instructor and provided by the person under restriction. 
     
     
         6 . The server device according to  claim 5 , wherein the content information includes at least one of provision time information related to a time for providing the predetermined service or location information related to a location for providing the predetermined service. 
     
     
         7 . The server device according to  claim 1 , wherein the usage related information includes unique information given to the instructor. 
     
     
         8 . The server device according to  claim 1 , wherein the usage related information includes information of an arbitrary character string selected by the instructor. 
     
     
         9 . The server device according to  claim 1 , wherein the authentication key information is generated based on one-time code information validated at a predetermined time in addition to at least one of the person-under-restriction related information or the usage related information. 
     
     
         10 . The server device according to  claim 9 , wherein the one-time code information is generated based on usage time information indicating a time when the person under restriction uses the restricted item. 
     
     
         11 . The server device according to  claim 1 , wherein the authentication is performed by the server device that has received the input key information input to the restricted item via a communication network. 
     
     
         12 . The server device according to  claim 1 , wherein
 the input key information is generated by the at least one processor and then transmitted to the restricted item via a communication network, and   the authentication is performed by the restricted item that has received the input key information generated by the at least one processor.   
     
     
         13 . The server device according to  claim 1 , wherein
 the input-key generation rule information and the authentication key information are transmitted to the restricted item via a communication network, and   the authentication is performed by the restricted item that has received the input-key generation rule information and the authentication key information.   
     
     
         14 . The server device according to  claim 1 , wherein
 the input key information and the input-key generation rule information are transmitted to a person-under-restriction terminal device possessed by the person under restriction via a communication network, and   the authentication is performed by the server device that has received the input key information input to the restricted item via the communication network and has received the input-key generation rule information from the person-under-restriction terminal device via the communication network.   
     
     
         15 . The server device according to  claim 1 , wherein
 the input key information and the input-key generation rule information are transmitted to a person-under-restriction terminal device possessed by the person under restriction via a communication network, and   the authentication is performed by the restricted item that has received the input-key generation rule information from the person-under-restriction terminal device and has received the authentication key information from the server device.   
     
     
         16 . A method for causing a processor to execute a process the method comprising executing on a processor in a computer the steps of:
 receiving at least one of person-under-restriction related information related to a person under restriction whose usage of a restricted item is restricted or usage related information related to usage of the restricted item by the person under restriction instructed by an instructor; and   generating authentication key information generated based on at least one of the received person-under-restriction related information or the received usage related information, the authentication key information being used to authenticate input key information generated based on predetermined input-key generation rule information and the authentication key information and input to the restricted item by the person under restriction, and to release restriction of the restricted item.   
     
     
         17 . A computer program product embodying computer readable instructions stored on a non-transitory computer-readable storage medium for causing a computer to execute a process by at least one processor so as to perform the steps of:
 receiving at least one of person-under-restriction related information related to a person under restriction whose usage of a restricted item is restricted or usage related information related to usage of the restricted item by the person under restriction instructed by an instructor; and   generating authentication key information generated based on at least one of the received person-under-restriction related information or the received usage related information, the authentication key information being used to authenticate input key information generated based on predetermined input-key generation rule information and the authentication key information and input to the restricted item by the person under restriction, and to release restriction of the restricted item.
